What this msg means?
Is there a possible way to remotely access to OSx?
I could ssh into the terminal. But when I try to do a startx, i get this message.

[root@localhost misc]# startx

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
giving up.
xinit: unable to connect to X server
xinit: No such process (errno 3): Server error.
[root@localhost misc]#

hi there,

means that your user - root ?? - has already a xsession running - active: under :0
like it is suggested, if this is not true, remove the file under /tmp and give it a second try.

Hi there,
Thanks for a quick replying.
hmm could it be local user already login?

I access the box remotely using ssh to the terminal.

Could I remotely access to OSx ? How do I do it?

hi there,

i didn't mean a local user. i meant the current user.
but i see that you have also the message with the "connection refused".
you could try to give a

Code:

xhost +

before the "startx" call.

hi there,

from xhost manual

Code:

DESCRIPTION
       The xhost program is used to add and delete host names or user names to
       the list allowed to make connections to the X server.  In the  case  of
       hosts,  this  provides  a rudimentary form of privacy control and secu-
       rity.  It is only sufficient for a workstation (single  user)  environ-
       ment,  although  it  does  limit  the worst abuses.  Environments which
       require more sophisticated measures  should  implement  the  user-based
       mechanism  or use the hooks in the protocol for passing other authenti-
       cation data to the server.

i think this has something to do with this error that you got

Code:

Xlib: connection to ":0.0" refused by server

so you run a "xhost +" allowing you to use the X server.
the message that you are already loggen is weird.
you should check the file under /tmp and remove it if you feel confortable.
a "ps" can give you the processes and clear this issue with the session that is already running.
this is what i know. if it is not clear, i hope some guru can join us.

Also if sshd of mac OSX is configured to forward X
/etc/sshd_config--> X11Forwarding yes

You can access your box with: ssh -X <your host>
(to access a Linux box, ssh -Y works better)

I am sorry what you mean by ssh -x and -y means?
I am using putty ssh to access the box/ Thansk

You could use XWin32 to get it work but I would rather use vnc server in OSX and an vnc client in windows
